Summary

A man who stabbed his 'friendly and soft-hearted' father 18 times during a psychotic episode has been found not guilty of murder by reason of insanity. Ross O'Rourke, who had a previous address in Tullow, Carlow, pleaded not guilty by reason of insanity to murdering his father, Stefan Nivelle Posschier, in Kinnegad, Co Westmeath in 2022. The jury returned a unanimous verdict in just 29 minutes, with the judge describing the trial as 'extremely difficult, especially for those who have lost a loved one.' Psychiatrists agreed that O'Rourke was suffering from a schizophrenic mental disorder at the time of the killing and met the criteria for the special verdict under the Criminal Law (Insanity) Act 2006. The trial heard that O'Rourke developed a delusion that his father was mixed up with criminals and the IRA and that he posed a threat to his life. He stabbed his father to death and then drove to a hospital, where he told his grandmother he had killed her son.
